Filed od. 15, 1958, ser. No. 767,376 i z ciaims. (ci. 98-101) In generalmy invention pertains to a household heating system in which air, heatedby a furnace, rises through ducts and passes through outlets orregisters in the walls of the respective rooms into said rooms.

More specifically, the invention is directed to the said outletscommonly known as registers. As a rule, a register includes a housinghaving a rectangular frame at the front portion thereof said frontportion projecting into the room in which the register is located. Theregister is mounted at the outlet end of an air duct and is of a size toexceed the area of the opening of said duct.

Disposed within said frame or forming a part thereof is a grill orscreen through which the air from the duet may pass into the room. Theregister includes also a damper which is located behind the grill andwhich may be operated from insidethe room 'by means of -a handleextending outwardly.

The housing of the register is permanently secured to the wall and noaccess may be had to the interior of the register without disconnectingthe whole front portion of the housing including the frame part. Thisprocedure may result in cracking the plaster in portions back of theframe and adjoining said frame.

In time, the air passing lthrough a register will deposit in itsinterior, including the damper, a quantity of dust, and as the frontpartion of the register, including said grill, is permanently set in itsplace, there is no way of getting into 'the interior of the housing forthe purpose of removing the dust. A removal of the housing or the frontportion of the housing, as the case may be, may result in cracking theplaster of the wall in portions in which the register is set, 'back ofsaid frame, and in portions adjoining said frame.

In view thereof, I have devised a register in which the grill at thefront of the housing is a separate element from other elements thereof,said grill being of a type which may be easily and readily Withdrawnfrom its normal location to afford access to the interior of saidregister.

I shall now describe my improvement with respect to the accompanyingdrawings in which:

Fig. 1 is a front elevational view of the register;

Fig. 2 is a Vertical sectional view of the register on line 2-2 of Fig.1, the view including a part of an air duet;

Fig. 3 is a' sectional view of the register on line 3-3 of Fig. 1;

Fig. 4 is a front elevational view of the frame of a modified register;

Fig. 5 is a front elevational view of a grill which is adapted to beused in conjunetion with 'the frame shown in Fig. 4.

Similar numerals refer to similar parts throughout the several views.

The register shown in the drawings includes a housing which is mountedclose to the fioor level 11 of a room, the front portion of the housingprojeeting forwardly of the surface 12 of |'the wall 13 of the room inwhich the register is located.

2,939,377 Patented June 7, 1960 rice The housing includes tworectaugular side walls 14, a top wall 15, and a bottom wall or 'base 16.At the front the housing is defined .by a marginal wall which formsarectangular frame. The frame is composed of two Vertical sides 17, atop portion 18 integrally connected to said sides, and a bottom portion19 being disp'osed in the same plane. Each of the side members 17includes a marginal portion or flange 20 which is bent inwardly so thatsaid marginal portion is disposed parallel to the respective side wall'14 of the housing (Fig. 3). Bach of said marginal portions 20 isprovided with a Vertical guding groove or channel 21 to which I shallrefer again. The top portion 18 of the frame includes a marginal portionwhich is bent inwardly to form a horizontal ledge 22 (Fig. 2). The ledgecontains a slot 23 which extends from one marginal portion 20 to theother.

The marginal portion 24 of the lower or bottom member 19 of the frame isbent inwardly to a position parallel to the bottom 16 of the housing,and contains a slot 25 extending from one marginal portion 20 to theother.

' The slots 23 and 25 are disposed in the same Vertical plane which alsopasses through the guiding Vertical grooves 21. v

Fitting into the slot 23 from above is a grill which has the form of arectangular plate having straight Vertical side edges 27. At the top themarginal portion of the plate is turned into a horizontal member 28which serves as a grip for the handling of the plate. The bottom edge ofthe plate is defined by a straight horizont-al line 29. The platecontains a central Vertical slot 30 which extends from a point close tothe top of the plate downwardly to a point close to its bottom edge '29.In addition, the plate contains a plurality of slots 31 which in thiscase are Vertical but in place of which the plate may contain any typeof openings, as the only object of having these openings is to provideoutle'ts from the duct into the room in which the register is located.

The side edges of the plate fit into the respective channels 21 of -theframe, while the lower end of the plate is adapted to enter into theslot 25 in the horizontal portion 24 of the bottom member 19 of theframe.

Hinged within the upper portion of the housing of the register, as shownat 32, and extending downwardly, is a flat damper 33 which normallycovers the opening 34 in the back of the housing of the register. Theopening forms an inlet into the housing from an air duct 35. The.damper' is provided with a handle 36 which passes through theaboVe-named slot 30 in the grill plate for manual operation of thedamper from inside the room in which the register is located.

A modified structure of the front portion of the housing and a modifiedgrill is shown in Fig. 4. The grill plate 40 is provided with a singlehole 41 at each side. The front end of the housing has the form of aframe 42 which, along its inner edge, has a marginal depressed portion43 for reception of the grill plate. A hole 44 in each side member ofthe frame serves for reception of fastening means, such as screws, whichmay be passed through the holes 41 in lthe grill and |threaded into therespective holes 44. The manner of securing the grill to the plate isonly suggestive, as any other means may be used for the purpose. A-hinged grill would 'be one example.

It will be noted that the grill plate contains a Vertical slot 45 foraccommodation of a handle, such as handle 36 shown in Fig. 2, and aplurality of slots 46 for passage of air therethrough.

After having described my improvement, what I wish to claim is asfollows:
